4 Replies and 224 Views Ramp in PS analysis with Sentinel-1  224  4 Started by  Maryse Hi everyone, I am working on a PS analysis with Sentinel-1 data. The processing worked fine, but when visualising the velocity in QGIS (_VD files), I get a north-south ramp over the whole area going from -20 to 20 mm/a. I am curious if anyone faced the same problem in the past or if anyone knows how to solve this issue I already tried to apply precise orbits for Sentinel-1, but it didn't change much in the resulting plots. All the best, Maryse

3 Replies and 612 Views Sarscape 5.2 SBAS processing Sentinel 1 _pwr_orb.sml file not found [EC:40002]  612  3 Started by  Zechao Bai Hi, I am processing a stack of Sentinel 1 radar images in Sarscape 5.2 in the second step of SBAS stacking an error comes out complaining FILE NOT FOUND referring to file: IS_20150519_m_0_20150531_s_1_original_master_pwr_orb.sml. Moreover, in the co-registration of second step one co-registration finished I need cancel, then begin, another continue. In short it's very slow. I understand the Sentinel 1 data match SARscape 5.2 software Thanks for any help.

0 Replies and 370 Views Export PS Points to Google Earth  370  0 Started by  Nathaniel Schaefer Thus far I have attempted to create and export kml files to Google Earth, but they have been much too large to be successful. As a workaround, I have been chipping the .png file to Google Earth and viewing the preliminary results that way. But with this method, point resolution is low and there is always at least a 5 meter offset from objects. Can anyone suggest a different way to view results Or am I doing something incorrect Thanks, Nate

We gonna to buy the computer but i dont know which parameters are the most important. I mean its better to buy ram of disk space I was heard tha this depends on used software. Could you advise something Cheers!

0 Replies and 259 Views Coherence optimization for dual polarized data  259  0 Started by  Sadra Kar Sarscape has some options such as "coherence optimizations" which is quite useful for a full polarimetric data (quad mode). But how we can get an optimized coherence map of dual polarized data (VV, VH) through Plarimetric Interferometry in Sarscape It seems only possible for full polarimetric (HH, HV, VH, VV) mode, is there any alternative way Please help me out. Thank you in advance.

4 Replies and 393 Views Processing of ALOS PALSAR for DEM extraction  393  4 Started by  Corsabrin Greetings! I am interested to extract an INSAR DEM from 2 scenes of ALOS PALSAR. So far, I have changed the grid size to 10 m. I have a couple of questions in regards to the GCP selection step: 1) How many GCP is needed Are there any tips other than using the .fint and .cc files 2) Which refinement method should be used Polynomial or automatic Mine defaults in polynomial mode. 3) How can I validate the extracted DEM Thank you and have a good day Regards Ben

1 Replies and 226 Views SLC scene selection for interferometry  226  1 Started by  Corsabrin Hi I have a generic question regarding the selection of SLC images for interferometry in SARSCAPE. I have read that ascending and descending should never be mixed. This I presume refers to the relative orbit number with respect to S1-A's data. For the same relative orbit, I noticed that frame numbers may be different as well. Are different frame numbers a cause for concern in the selection of SLC images for interferometry, especially PSinSAR/SBAS Regards Chad

I understand at least 20 images is recommended. In my test, during the First Inversion step, the processing is stuck at: 'preliminary candidates selection' for quite some time. I have been waiting at this step for about 24 hours. Anyone has any idea what is going on Do I continue waiting or is there already a processing error Or is it because I need to use > 20 SLCs For your information, the preliminary candidates sele...
